EDGE ROLL Filed D90. 50, 1955 I M9 M12. czafirm Patented July 16, 1935 UNITED STATES PATENT OFFICE 1 Claim.

The object of this invention is to provide an improved edge roll for upholstered furniture.

The invention and the various specific objects thereof will be more readily understood from the attached drawing, in which:

' Figure 1 is a view in perspective of a section of edge roll made in accordance with my invention, and

Fig. 2 is an end view of the roll section shown in Fig. 1.

With reference to the drawing, the edge roll consists in general of a shaped core I and a suitable embracing cover consisting in the present instance of an inner layer of felt 2 and an outer embracing casing 3 of burlap. The cover consisting'of the felt 2 and burlap 3 is extended from the rear Wedge-shaped edge of the core I to form an extension 3, and stitches are taken in this extension 4 to hold the cover in place, the stitches in the present instance being made in a plurality of series extending longitudinally of the edge roll. The innermost series of stitches preferably and as shown extends immediately in back of the rear edge of the core so that the cover 2-3 neatly embraces and conforms to the shape of the core.

With particular reference to the core, it will be noted that this element of the edge roll is shaped to provide a substantially flat base 6 which terminates at the forward end in a rounded upwardly inclined curve 1, and this forward surface I merges at the top into a smoothly rounded top surface 8 which at the rear falls away'on a relatively sharply inclined rearward surface 9 which converges at an acute angle with the flat base surface 6 to form the wedge shaped rear edge of the core. It will be noted that the forward curved surface 1 extends throughout at substantially the same inclination to the base surface as the rear face 9, which it accordingly substantially parallels. This form of corein addition to providing an extended flat supporting or base surface affords the required maximum height closely adjacent the front edge of the core and. at the same time by reason of the inclination of the forward and rear upper surfaces 1 and 9 avoids all unnecessary bulk, and in this latter respect reduces the edging to a minimum practicable size. By reason of the closely fitted character of the cover elements 2 and 3 and the fact that the inner series of stitches 5 extends through the cover at a point immediately adjacent the rear edge of the core I, the cover takes substantially the same external form as the core; and by reason of the fact that the stitches 5 are confined to the cover elements at the rear of the core and do not enter the latter, the entire forward or effective surface of the edging is smoothly finished and free from irregularities.

As previously set forth, the outer surface of the edging takes substantially the exact form of the core I, having a flat under or base surface and a maximum height relatively close to the forward face together with the sharp rearward inclination terminating in the extension 4. This extension provides means for securing the edging to the framework or other part of the furniture without affecting the form of the working portion of the edging, and also affords considerable leeway in adjusting and fittingthe edging to the furniture. The edging thereby is'made readily adaptable to practically all parts of the furniture where edging is required.

An important feature of the invention resides in the material of which the core is made. This core preferably is made of twisted or crushed and shaped tissue paper or a combination of tissue and Kraft or other papers or materials. I have discovered that tissue paper is particularly well adapted for this purpose, in that it possesses a marked tendency to resist permanent deformation and has a high degree of resiliency. This overcomes a great difficulty in the manufacture of edge rolls, since it affords the necessary stability of form Without rigidity.

My use of tissue in conjunction with the par--. ticular form described above provides an edge roll of .greatly improved characteristics. The flat supporting or base surface makes it possible to support the roll over a substantial portion of its entire lateral area, and the characteristics of'the core and of the padded cover give the roll the necessary softness and ability to give under pressure without tendency toward permanent deformation. At the same time, the edge rollis relieved of all unnecessary bulk and has a high adaptability for use in all parts of the furniture where such edging is required. The construction and composition described also permit bending of the edge roll in almost any direction to con.- form to the curves of the furniture frame to which it may be attached.

It will be understood that the invention is not restricted in its broader aspects to the particular preferred materials named above, and that the benefits of the invention may be realized in various degrees with the use of the other materials commonly used in the manufacture of products of this general character.

I claim:

An upholsterers edge roll of the character set forth comprising a pliable, highly resilient and stable core consisting of twisted tissue paper, and a flexible envelope closely embracing said core.
